Using EZware-5000 61XY PlotThe XY Plot Object is used to plot one series of values against another series of values on a line graph.The direction of the plot is defined in the Direction field as follows:DirectionRightLeftUpDownResultThe origin is at the lower left. The X-axis moves to the right, the Y-axis moves up.The origin is at the lower right. The X-axis moves to the left, the Y-axis moves up.The origin is at the lower left. The X-axis moves up, the Y-axis moves to the right.The origin is at the upper left. The X-axis moves down, the Y-axis moves to the right.The No. of channels field specifies the number of datasets to plot (up to 16 channels).The Control Address specifies the address to use to control how the XY Plot operates. The following values can bewritten to the Control Address to control the plot:Trigger ValueControl Function1 Draws the plot for the selected channel, leaves existing data.Can display up to 32 plots for 1 channel, 16 plots for 2 channels, 8 plots for 4 channels, etc.2 Clears the plot for the selected channel.3 Clears the plot for the selected channel, then redraws the plot with the current data.The HMI will write a 0 to the Control Word address after the operation is complete.The No. of data address field is automatically assigned to the next consecutive address after the Control Address. Itmust be loaded with the number of pairs of X-Y data to plot. This value must be set before a trigger value is written tothe Control Address. Up to 1023 data points can be plotted per channel.The Read address field is the starting address of the data to plot. Each channel has its own Read address. Normally,the X and Y data are read from two consecutive addresses beginning with the Read address. To have the XY Plot useseparate addresses for X and Y data, check the Separated address for X and Y data checkbox. Separating the X and Ydata addresses also allows the X and Y data to have different formats. The first Read address field defines the X-axisdata and the second Read address field define the Y-axis data.The X-axis and Y-axis scaling is configured in the Limits section on the General tab. The Low and High limits define theleft-to-right range and the bottom-to-top range for the X-axis and Y-axis respectively.If Dynamic limits is checked, the limits are read from registers determined by the Read address as follows:With Separated address for X and Y data uncheckedRead addressRead address + 1Read address + 2X minimumX maximumY minimum0600-0069-0000 Rev.
